(NBC) — Tuesday night will be an emotional one for fans of NBC’s “This Is Us” with the airing of the series finale and it is emotional for the cast as well.

In a recent interview, Mandy Moore, who has played Rebecca Pearson for the past six years, talked about saying farewell to her character and what is next for her when the series ends.

Moore and her “This Is Us” castmates wrapped up shooting the series about three weeks ago, Tuesday the last episode will air on TV.

“I think watching the end of the series, along with the audience will probably make it feel more real,” said Moore. “Right now. I’m still kind of in disbelief that it’s over.”

Last week, the children of Moore’s character, Rebecca, said goodbyes to their dementia-stricken mother even as she experienced a dreamlike farewell aboard a train.

When asked about how much she would miss playing Rebecca, Moore said it was not going to be easy.

“I get emotional thinking about it,” said Moore. “It’s hard. I feel like saying goodbye to my, my family and my friends was really hard. But like, I haven’t really come to terms with the fact that I have to say goodbye to her yet. Like, I have to detach from her.”

She also revealed how playing the character will have a profound impact on the rest of her life.

“I get to live with this woman inside of me forever now,” said Moore. “I have sort of this template, this guidepost of what it means to be a mom and what it means to love your family unconditionally, and, and how, what a gift.”

Moore will have her son Gus in tow next month for her first concert tour in 15 years supporting her new album “In Real Life” and its title track.

“My husband, Taylor, who’s a musician, he and I wrote the whole record together, it was like, our way of finding catharsis during a strange time was just to lean on music and turn to each other and to write,” said Moore.

It’s a new opportunity she is looking forward to easing the loss of the series.

“To take the music on the road with my husband, you know, kind of a family adventure this summer, is also a great way to process my emotions of, of ending this really significant chapter of my life with ‘This Is Us,’” said Moore.

And Moore knows fans will be processing emotions as well.

“I think people are going to be very satisfied with the way things are wrapped up because they’re not completely wrapped up, because that’s not realistic to life. Right?” said Moore. “I think it will be very satisfying.”

As only the Pearson family can say goodbye.

Watch the series finale of “This Is Us”  Tuesday at 9 p.m. on News 2.

About ‘This Is Us

Everyone has a family. And every family has a story.

“This Is Us” chronicles the Pearson family across the decades: from Jack (Milo Ventimiglia) and Rebecca (Mandy Moore) as young parents in the 1980s to their kids (the big three), Kevin (Justin Hartley), Kate (Chrissy Metz) and Randall (Sterling K. Brown) searching for love and fulfillment in the present day along with Toby (Chris Sullivan) and Beth (Susan Kelechi Watson).

This grounded, life-affirming dramedy reveals how the tiniest events in our lives impact who we become, and how the connections we share with each other can transcend time, distance and even death.
